 - [x] Callback-Endpoint `/auth/callback` im FastMCP-Server ergänzen
 - [x] `STRAVA_REFRESH_TOKEN` automatisch in `.env` zurückschreiben nach Token-Rotation
 - [x] Optionaler Hinweis beim Start falls kein Token vorhanden ist

+## Bugs
+- [x] Server startet nicht ohne Refresh Token. Brauche Möglichkeit das ich Auth über Agentgateway machen kann, damit ich nicht jedes Mal manuell den Auth Prozess anstoßen muss. Siehe Gitea MCP Server.
+- [x] Hinweise für Model wie das Datum ausgegeben wird vom MCP Server. Aktuell ist das LLM oft unsicher bzgl. datums formates.
